DEVICE FOR CAPPING- OFF GLASS CYLINDERS.

Specification of Letters Patent.

Patented Dec. 7, 1915.

Application filed August 18, 1914. Serial No. 857,351.

To all whom it may concern:

Be it known that 1, CHARLES Lsnnsnnr'r, a citizen of the Unlted States, and resident of Mount Jewett, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Capping ()fl? Glass Cylinders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in devices for capping off glass cylinders, the object of the improvement being to provide a device composed of few parts and of Fi 2 is a'similar view showin it in its closed position, and the electric wire encircling the glass cylinder.

A A represent the two halves of a circle which are preferably formed of aluminum pipe sections, which are hinged together at B. and are insulated from each other.

C C represent the terminals with which the leading-in wires D D are connected.

The free ends of the semi-circular sections A A are provided with insulated handles, E. E and with clamps F F or other suitable supports for the ends of the heating wire G. One end of the heating wire is permanently secured to the clamp or support F, while the other end of the wire passes around a roller 9 attached to support F and around the drum of a reel H which is secured to section A of the device and is insulated therefrom.

The device ispr'eferably' suspended from an overhead track way bymeans of a wire H which is insulated from the circular frame A A. To insure the alinement of the ends of the heating wire when current is passing through it, one of the clamps orsupports F circle the glass cylinder.

is provided with a tenon it which enters a socket [L1 in the other clamp F or the tenon and socket or other equivalent means maybe attached to the free ends of the semi-circular sections A A itbeing understood of course that the clamps or supports and tenon and socket are so constructed and made of suitable material to insure the electrical insulation of the two sections at their free ends as well as at their hinged ends.

The operation of the device is as follows: After a glass cylinder of any length has been placed upon a capping-0d horse, the circular support is moved lengthwise of the cylinder to the point at which it is desired to sever the cylinder, and the two hinged sections are opened so as to permit them to bemoved laterally above and below the cylinder and then by closing the sections together, the heating wire is caused to en- The handle of the reel is then rotated to cause the heating wire to be brought into snug contact with the cylinder. The circuit is then closed by a suitable switch, not shown, which causes the current to flow from one of the leading-in wires D through section A of the circular frame and from there through clamp F to and through the heating wire G, to clamp F and from thence through the other semi-sphen' ical section A to the other leading-in wire D The electrical resistance of the heating wire G is sufliciently great to cause the wire to be heated to incandescence by the passage of a suitable current through it, and this high degree of heat will enable the cylinder to be capped oil on the heated line. The slight space of the cylinder between the two ends. of the heating wire may be heatedby slightly rotating the circular frame A A while current is passing through the heating wire.

()ne of the advantages of my improvement is, that it provides a supporting frame for both the leading-in wires and the heating wire, which permits the latter to be passed around the glass cylinder and drawn snugly in contact therewith without requiring the operator to touch the heating wire and hence shields him from the danger of injury due to electric shocks.

It is evident that many changes might be made in the construction and relative arrangement of the parts of my improvement without departing from my invention and I claim as new and desire to secure by Letters-Patent, is

The combination of a frame consisting of two sections hinged together and each provided at its free end With a handle whereby both handles may be grasped by one hand When the frame is closed around a glass cylinder, a heating Wire having one of its ends secured to a terminal at the free end of one of the hinged sections and engaging a terminal at the free end of the other hinged section, a take up device for the free end of said Wire, and a flexible suspension device 'in which one of said hinged sections has free sliding movement.

In testimony whereof, I have signed this specification in the presence of two subscribing Witnesses.
